GitHub API Guide

Overview

This skill provides tools to interact with the GitHub API using Python. It enables listing repositories (public and private), retrieving repository details, and more.

Authentication

OAuth Authentication (Recommended)

This skill uses GitHub OAuth authentication through the Datalayer identity system. When you connect your GitHub account via the "Connect GitHub" button in the agent configuration form, the OAuth token is automatically available to this skill.

How it works:

1. Click the GitHub connect button in the Agent Configuration form
2. Complete the OAuth authorization flow
3. Your GitHub access token is securely stored and automatically provided to skill scripts

The token is retrieved from the identity store and made available as the GITHUB_TOKEN environment variable when scripts are executed.

Required OAuth Scopes

When connecting your GitHub account, ensure the following scopes are granted:

• repo - Full control of private repositories (required for private repos)
• read:user - Read user profile data
• read:org - Read organization data (if listing org repos)

Manual Token (Fallback)

If not using OAuth, you can set the GITHUB_TOKEN environment variable manually:

export GITHUB_TOKEN="ghp_your_token_here"

To create a Personal Access Token:

1. Go to GitHub Settings > Developer settings > Personal access tokens
2. Click "Generate new token" (classic)
3. Select the scopes listed above
4. Generate and copy the token

Token Permissions

Scope	Description	Required For
repo	Full control of private repositories	Private repos, creating issues/PRs
public_repo	Access public repositories only	Public repos only (limited)
read:user	Read user profile data	User information
read:org	Read org membership	Organization repos

Note: The OAuth flow requests repo, read:user, and read:org scopes by default.

Quick Start

import os
import httpx

token = os.environ.get("GITHUB_TOKEN")
headers = {
    "Authorization": f"Bearer {token}",
    "Accept": "application/vnd.github+json",
    "X-GitHub-Api-Version": "2022-11-28",
}

# List your repositories
response = httpx.get(
    "https://api.github.com/user/repos",
    headers=headers,
    params={"per_page": 100, "type": "all"},
)
repos = response.json()

for repo in repos:
    visibility = "🔒" if repo["private"] else "🌐"
    print(f"{visibility} {repo['full_name']}")

Working with Issues

    """List issues for a repository.

    body: str = "",
    labels: list[str] = None,
) -> dict:

Working with Pull Requests

List Pull Requests

def list_pull_requests(
    owner: str,
    repo: str,
    state: str = "open",
) -> list[dict]:
    """List pull requests for a repository.

        headers=headers,
        params={"state": state, "per_page": 100},
        timeout=30.0,
    )
    response.raise_for_status()
    return response.json()

Error Handling

import httpx

def safe_github_request(url: str, headers: dict) -> dict | None:
    """Make a GitHub API request with error handling."""
    try:
        response = httpx.get(url, headers=headers, timeout=30.0)
        response.raise_for_status()
        return response.json()
    except httpx.HTTPStatusError as e:
        if e.response.status_code == 401:
            print("Error: Invalid or expired GITHUB_TOKEN")
        elif e.response.status_code == 403:
            print("Error: Rate limit exceeded or insufficient permissions")
        elif e.response.status_code == 404:
            print("Error: Resource not found")
        else:
            print(f"HTTP error: {e.response.status_code}")
        return None
    except httpx.RequestError as e:
        print(f"Request failed: {e}")
        return None

Rate Limiting

GitHub API has rate limits:

• Authenticated requests: 5,000 requests per hour
• Unauthenticated requests: 60 requests per hour

Check your rate limit status:

def check_rate_limit() -> dict:
    """Check GitHub API rate limit status."""
    headers = get_github_headers()
    response = httpx.get(
        "https://api.github.com/rate_limit",
        headers=headers,
        timeout=30.0,
    )
    response.raise_for_status()
    return response.json()

Common Patterns

Filter Repositories by Language

def list_repos_by_language(language: str) -> list[dict]:
    """List user repositories filtered by primary language."""
    repos = list_repos()
    return [r for r in repos if r.get("language") == language]

Get Recent Activity

def get_recent_repos(days: int = 30) -> list[dict]:
    """Get repositories updated in the last N days."""
    from datetime import datetime, timedelta

    cutoff = datetime.now() - timedelta(days=days)
    repos = list_repos(sort="updated")

    recent = []
    for repo in repos:
        updated = datetime.fromisoformat(repo["updated_at"].replace("Z", "+00:00"))
        if updated.replace(tzinfo=None) > cutoff:
            recent.append(repo)
    return recent
